In Provence: Avignon - Camping Pont d'Avignon, Camping Nostradamus at Salon de Provence, Selection Camping and Camping Cros du Mouton at Cavalaire sur Mer.
Outside of Provence in the Languedoc/Rouisillon area: Camping Neptune at Grau d'Agde is within walking distance of the 'village' of Grau d'Agde and also the larger town of Agde itself (and also within walking distance of the Canal du Midi).
Camping Beau Rivage is 'at the entrance to the charming village of Meze', Camping Le Haras at Palau del Vidre is walking distance into the village, and I'm sure there are loads of others.
